Title    Analysis and test of the Internet of things    

Abstract

In recent years, the Internet of Things is developing rapidly. It is wildly used and plays an important role in smart home, smart transportation, smart grid, smart logistics, smart agriculture, smart power, and smart industry.

The performance indexes of IOT are mainly the survival time of the network, the data transmission rate, transmission delay and so on. Based on these indexes, the thesis aims at making a summary of commonly used performance improvement methods of topology control and data fusion, and also making an analysis of the reasons why these methods can improve performance in actual application situations. Trough observing the result of the experiments in communication distance, simple handshake agreement, transmission power and communication channel, the existing agreement will be concluded. In addition, the experiment is largely completed on the MC13213 wireless communication module. The ZigBee technology applied in the experiment at the same time, analyzed the performance of the same node under different environmental conditions, on the Internet of things had the further understanding and communication performance.

Key words: the Internet of Things; communication channel; handshake agreement; MC13213；ZigBee
